Lowering hardness?

[tommyfish]

I know that water changes are the best, but is there anyway to help lower the hardness a little faster. I my 220 is VERY high, a water changes are taking a long time. Just thought I would ask.
Thanks for any help.

Are you speaking of dkh? What are you using to test with?

I'm sorry yes I am referring to dKh. I am using aquarium pharmaceuticals brand. I have been using tap water until recently when I got my ro/di unit installed. The city water is at 28dKh.
Thanks

You really don't want to lower it fast. Just keep up with what you're doing unless it's causing immediate harm.
